[Aortopulmonary fistula with interventricular defect and pulmonary valve stenosis in a 15-year-old girl. Surgical correction].

A young girl of 15 with an aorto-pulmonary fistula was treated surgically, with a successful outcome. The clinical diagnosis could only be established at right-sided catheterisation, and especially at retrograde per-arterial aortography. The small size of the fistula explains the low level of the pulmonary arterial hypertension, and the way in which the condition was well-tolerated for some time. The association of this lesion with ventricular septal defect and pulmonary stenosis is extremely rare.

[Diastolic compliance and indices of contractibility in aortic insufficiency].

A cine-angiographic study was carried out in eleven patients with major aortic incompetence, in two of whom there was an associated aortic stenosis. The ventricular end-diastolic volume is always greatly increased, disproportionately to the modest increase in end-diastolic pressure. The pressure-volume relationship during filling is therefore altered, and makes it possible for a normal end-diastolic compliance (dV/dP) TD to be preserved. The indices of contractility are markedly altered, despite the recent appearance of signs of poor tolerance. These findings argue in favour of a full haemodynamic investigation and of early corrective surgery.

[Supravalvular ring type aortic stenosis with hypoplasia of the ascending aorta and stenosis of the origin of the innominate artery. Surgical correction].

The authors report the case of a 19 year old woman with supravalvar aortic stenosis and hypoplasia of the ascending aorta with stenosis at the origin of the innominate artery. This was a sporadic form, without mental deficiency nor facial dysmorphia. No similar case was found in the family. The patient had three attacks of bacterial endocarditis over a period of 3 years and became cured without any cardiac sequelae. In view of the onset of left ventricular failure and sequelae. In view of the onset of left ventricular failure and syncope, operation was decided. A lozange-shaped patch was placed on the aorta from the narrowed supravalvar part to the origin of the innominate artery and prolonged on the latter vessel after relief of the stenosis. This gave an excellent result.

[Istope examinations in coronary intensive care units].

Radio-isotopes may be of use in investigation of patients with heart disease on an intensive care unit. These investigations are not traumatic. The radio-isotopes are innocuous and reliable, the examinations may be easily repeated and are therefore of great interest in diagnosis and prognosis of cardiovascular disease.

[Indications for permanent electrosystolic pacing in arrhythmia revealed or aggravated by treatment].

The authors report 25 cases of patients, average age 67 years with severe coronary or valvular heart disease, with conduction disorders. The conduction disorder occurred alone in 8 cases and was associated with a disorder of excitability in 17 cases. It was either obvious, as in 14 cases, or latent, as in 11 cases, and precipitated by various forms of treatment, the disadvantage of which was the negative dromotrope effect. This treatment was prescribed for permanent resting angina (amiodarone and prenylamine), heart failure (digitoxin) or excitability disorder (beta-blockaders or procainamide). 11 patients had one or several fainting attacks. Permanent electro-systolic pacing with stimulation on demand, is necessary in all patients to palliate the consequences of treatment. In 11 cases out of 25, prior temporary pacing permitted the authors to assess the efficacy of treatment. The high post-operative mortality (40%) is not due to the apparatus but depends on the severity of the coronary heart disease or heart failure in these patients, In 60% of cases, the result of stimulation was excellent and was maintained permanently.

[Study of changes in myocardial contraction and left ventricular diastolic regidity after aortocoronary bypass].

Eighteen patients with coronary insufficiency underwent a left ventricular cineangiography before and an average of four months after aorta-to-coronary bi-pass in order to assess the post-operative changes of myocardial contractility and diastolic rigidity. The contractility indices (VCF: mean speed, and VCF max: maximum shortening speed of the equatorial diameter of the left ventricle (% delta theta) were unmodified in the group (I) of fourteen patients with at least one pervious by-pass. On the contrary, a decreased % delta theta was observed in the group (II) of four patients in whom all the by-passes were occluded. The left ventricular end-diastolic pressure (LVEDP), the end-diastolic volume (LVEDV) and the "normalized" rigidity index (K) were unmodified in both groups after operation. The cardiac rate increased in the post-operative period in the group I (p less than 0.01) and the whole of the 18 patients (p less than 0.001); there was a positive correlation (p less than 0.02) between this variation and that of VCF, VCF max. and % delta theta, the significance of which is discussed. Besides there was a negative correlation between the variations of LVEDV and the VCF, and between the equatorial end diastolic diameter of the left ventricle and VCF, VCF max. and % delta theta, both in the pre-operative and the post-operative periods.

[Unruptured aneurysms of Valsalva sinus of septal origin].

Aneurysms of Valvsalva sinus unruptured into a cavity, but developing into the membranous and even muscular interventricular septum are exceptional. Two cases illustrating this fact are reported. In one of them, a massive mitral incompetence by elongated chordae tendinae related to the presence of a voluminous intra-septal pouch. Atrio-ventricular and intraventricular conduction disturbances were present in both patients. The interest of supra-valvar angiography which makes it possible to advise operation before the eventual rupture is underlined.

[Study of interventricular septal defects with equal aortic and pulmonary artery pressures. Classification by clinical and computer methods of 70 cases].

Application of various methods of classification to a group of 70 cases of ventricular septal defect with high pulmonary artery hypertension allowed a comparative study between the various methods aiming at distinguishing the forms with low from high pulmonary artery resistance. The reference clinical classification provides supplementary informations derived from the natural or post-operative course and eventually from the microscopic examination. The first automatic classification relies on the study of a single criterion: the pulmonary arteriolar resistance and the systemic resistance ratio. A second classification is based on the attribution of points to some clinical or haemodynamic signs resulting in a score orienting the classification of every individual. Multifactorial analysis methods deal with all the available informations for the overall group, and suppose the use of a computer. The informatic methods make it possible to study the classifying value of every sign. Correlations were established between these various techniques and the medical classification.

[Myocardial infarct due to diffuse arteriopathy of the coronary trunk in a 13-year-old child].

A case of antero-septal myocardial infarction in a child of 13, presenting as syncopal attacks, is reported. Selective coronary angiography showed severe diffuse lesions of the anterior descending artery and the right coronary artery. Clinical progress was satisfactory over an 18 month follow-up period. The only biochemical abnormality was a raised serum uric acid, the significance of which is discussed.

[Phonomechanography of recent myocardial infarct: the jugulogram and carotidogram].

The mechanographic tracings of 30 patients with recent myocardial infarction, usually uncomplicated and without mitral incompetence, were compared with those of two control groups. The jugular venogram was unhelpful; full measurements can be made in only 40% of cases, and the scatter of normal values is too great. The carotid arteriogram is usually of the "arterial" type. Transmission time and the duration of the rising phase were both shortened. These findings result from the high level of peripheral resistance. The mean left systolic time was, except for qB2, abnormal, and remained so at the end of the first month. In this series there were neither maximal changes in J3, nor significant improvement from J12 nor J30. The largest increases in PPE and PPE/LVET were found in cases with large infarcts, and the largest reduction of LVET was in a case with left ventricular failure. There was no particular peculiarity corresponding with the site of the necrosis. Alteration in the ratio PPE/LVET is often a lasting measure of depressed left ventricular function. It would be most useful to study this ratio in the long term and to use it as a measure of recovery of function and as a guide to advising the patient on his future life style.
